Abstract

A portable antenna system includes an antenna that is substantially defined by one or more portions that include electrically conductive self-similar extensions. The system also includes an article of clothing in which the antenna is attached to a surface of the article of clothing such that electrically conductive self-similar extensions extend across the surface of the article of clothing.

Claims

1. A portable antenna system comprising:

an antenna that includes (i) an electrically conductive portion including electrically conductive traces each including a fractal pattern based on an acute angle, and (ii) an electrically non-conductive portion that structurally supports the electrically conductive portion; and

an article of clothing, wherein the antenna is fixedly attached to a surface ofthe article of clothing such that electrically conductive traces extend across the surface of the article of clothing.

2. The portable antenna system of claim 1, wherein the traces include two or more angular bends.

3. The portable antenna system of claim 1, further comprising:

a co-planar feed connected to the antenna for transmitting and/or receiving electromagnetic signals through the antenna.

4. The portable antenna system of claim 1, wherein the antenna is configured to transmit electromagnetic energy across a spectral bandwidth that is defined by a ratio of at least 5:

1.

5. The portable antenna system of claim 1, wherein the antenna is configured to receive electromagnetic energy across a spectral bandwidth that is defined by a ratio of at least 5:

1.

6. The portable antenna system of claim 1, further comprising:

a dielectric plate to which the antenna is mounted.

7. The portable antenna system of claim 6, wherein the dielectric plate is capable of deflecting projectiles.

8. The portable antenna system of claim 1, wherein the antenna is mounted on an internal clothing layer of the article of clothing.

9. The portable antenna system of claim 1, wherein the antenna is mounted to an exterior surface of the article of clothing.

10. The portable antenna system of claim 1, wherein the article of clothing is a vest.
